The easiest way for a MLCer to get a Do-Over of their perceived lost youth that they are grieving ... is to go back to the glory days and hook up with someone they were once with, or wanted to be with, etc.
Perhaps it completes an old unresolved fantasy, or just gives them fuel for a new one.
Not only do the MLCers find someone they would never have been seen in public with a couple years ago, they are not the person you knew a couple years ago. The MLCer is like an alien shape changer, trying to be the person they wish they had been. And they try hard. This becomes easier for them and more within their grasp as they burn down and destroy all previous life as they knew it. What they can't erase or destroy, they re-write to fit this new fantasy.
Keep reading, posting and venting here. It will help you gain some perspective on MLC. But focus most on the threads or notes explaining how important it is for you to continue to live for yourself, and improve yourself. This you will value the most once you find yourself in your better life. If there is ever any taste for revenge, understand that the best revenge is in living the better life.
